Severe thunderstorms moved east-southeastward from the western High Plains across Nebraska, northern Missouri, and into Illinois during the late afternoon yesterday and last night. Map of storm reports received at the SPC shown above. Map below shows yesterday's 1300 UTC Outlook with verification superposed through midnight CST. The outlook verified quite well. There are two strange appearing, isolated wind reports in New Mexic, east of the Sandia Mountains around Clines Corners. I took a look at regional radar around the time of the reports and there were indeed isolated thunderstorms in that area. Soundings indicate very high cloud bases (probably around 500 mb) and the storms produced local downburst(s) that produced damage and an ASOS-measured gust over 60 mph.
The afternoon severe thunderstorms over the Plains grew into two large, nocturnal MCSs that merged around midnight over the lower Missouri River Basin - above IR image is from the PSU E-Wall and is for 0615 UTC on 4 June. The very cold cold tops associated with the MCS cores are reaching to nearly -80C!
Meanwhile, TS Boris had a brief life as it developed and moved ashore in far southern Mexico. Map below from NHC shows Boris as a weakened depression. The remnants of Boris are moving slowly northward across the lowlands of the Isthmus of Tehuantepec. The remnants may eventually reach the Bay of Campeche, moving into the Atlantic Basin.
